Containers Docker Containerization

Purpose

Docker container running Alpine Linux that automates and improves upon much of the script mentioned in the Git Repo Updater document. It offers the additional benefits of checking for updates every 5 seconds instead of every 60 seconds. It also accepts environment variables to provide credentials and notification settings, and can have an infinite number of monitored repositories.

!!! info "Earlier Configuration Delivery Approach" The Gitea runners blog records replacing this polling approach for the documented configuration-delivery use case. The configuration-delivery reference links both runner implementations and this retained watcher deployment.

Deployment

You can find the current up-to-date Gitea repository that includes the docker-compose.yml and .env files that you need to deploy everything here

version: '3.3'
services:
    git-repo-updater:
        privileged: true
        container_name: git-repo-updater
        env_file:
            - stack.env
        image: git.bunny-lab.io/container-registry/git-repo-updater:latest
        volumes:
           - /srv/containers:/srv/containers
           - /srv/containers/git-repo-updater/Repo_Cache:/root/Repo_Cache
        restart: always

Build / Development

If you want to learn how the container was assembled, the related build files are located here

# Use Alpine as the base image of the container
FROM alpine:latest

# Install necessary packages
RUN apk --no-cache add git curl rsync

# Add script
COPY repo_watcher.sh /repo_watcher.sh
RUN chmod +x /repo_watcher.sh

#Create Directory to store Repositories
RUN mkdir -p /root/Repo_Cache

# Start script (Alpine uses /bin/sh instead of /bin/bash)
CMD ["/bin/sh", "-c", "/repo_watcher.sh"]

Save the complete Git Repo Updater script as repo_watcher.sh next to the Dockerfile before building the image.
